As developers move to microservice-centric designs, components are broken into independent services to be developed, deployed, and maintained separately. IDC predicted, by 2022, 90% of all applications will feature microservices architectures that improve the ability to design, debug, update, and use third-party code. Easier to deploy.

There are lots of ways to solve a given programming problem; but most of us have some ideas about what makes code “good” or “bad.” Given enough unit tests and acceptance tests, we can imagine a system for automatically generating code that is correct.

First, a bit of operating-system design context. It is desirable for a program to be able to go to sleep and then wake up a little while later. Ideally the CPU goes to sleep when Sleep(1) is called, in order to save power, so how does the operating system (OS) wake your thread if the CPU is sleeping? Decades of madness.

The more advanced the system, she observed, “the more crucial…the contribution of the human operator.” RPA explained.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. We formulate the problem as a Mixed Integer Program (MIP). can we actually make this work in practice?
